Anyone know why the washington has 2 different hardware layouts
was looking at them and i saw some had like a full cabinet where the tv goes in the back, and some had like a computer desk.Also some models had round end cabinets over the theatre seating and around the island which open up on each side?same model year 2014

If it's the same model, the only thing that I could see is they had a mid-year change in the design. One could be an early build, same as the 2013 but with the 2014 model year and one a later year build. Especially now that the 2015's are already out and the 2014 models have been built over the last year. Check the build date.

Just a FYI: We have the Rushmore Lincoln. Our unit had several redesigns in the months of 2013- 2014. The floorplan now has been entirely redesigned (So glad we purchased when we did!) do to a change in the frame they use. Redwood has had an effect on all the Rushmores. They're now being made in the Redwood factories. Our 2014 Lincoln has an exterior dedicated Docking Center. We do not think there is another of our model that has one. So it doesn't surprise me those changes effected the Washington Models also.
